By-products of bacterial metabolism, called volatile sulfur compounds, create the odor that most of us associate with bad breath. Dentists note that over 85% of Americans suffer from bad breath at some time. Bad breath may be caused by medical conditions, such as esophageal reflux and hiatal hernia, or it may come from oral sources: cavities, gum disease, and coatings on the tongue. Bad breath herbal remedy is recommended by many doctors and practitioners of holistic medicine. A bad breath herbal remedy treatment also helps healthy teeth and gums, preventing canker sores, receding gums, periodontal disease and other dental health problems.
